I have a issue while playing BF3 in Crossfire, The cards seem to be getting a FPS drop while playing the game this doesnt matter what settings I have it, It could be on the lowest settings and still get a massave drop.

Drivers and caps right now are from what you get from 12.7, BF3 is the only game I was playing on the machine as thats the one I wanted to make sure was running with the setup, I have now installed another 4GB 2x2 into the machine bringing the machine up to 7GB, wasnt what I wanted to do as it might upset the whole 3 channel but ill give it a shot and let you know.

I have also installed Diablo 3 and running with crossfire with the 7GB can't tell you the FPS results as it keeps saying it's 0 FPS so I don't know if it's broke or not
